2. Safety Issues in ICU
• More than 5 million patients are admitted to intensive
care units each year in the United States.
• Mortality rates in patients admitted to the ICU average
10% to 20% in most hospitals.
• Overall, approximately 200,000 patients die in U.S.ICU
each year.
3. Safety issues in ICU
Classification of incidents used in the Australian AIMS
• Airway and ventilation: e.g. unplanned extubation and
disconnections.
• Drugs and medications: e.g. allergic reactions and drug
errors.
• Procedures, equipment and catheters: e.g. inadvertent
carotid artery cannulation.
• Patient environment: e.g. a lack of appropriate beds
causing pressure sores.
• ICU management: e.g. incidents caused by an over reliance
on agency staff.

11. Unplanned endotracheal extubations in ICU
Unplanned extubation rate; 0.1~3.6/100 intubation days.
Risk factors;
male gender, APACHE score≥ 17(OR9.0), COPD,
restlessness/agitation(OR3.3-30.6),
lower sedation level(OR2.0-5.4),
Higher consciousness level(OR 1.4-2.0),
Use of physical restrains (OR3.1).
Reintubation rates 1.8-88% of unplanned extubation.
Preventive measures; Standardization of procedures,
staff education, staff surveillance & identification &
management of high risk patients -
decreasing rate; 22~53%
Best methods; securing E tube & use of Physical
restraints ??

16. Case; SNUH adult ICU
• A case-control study over 3 years period from
January 1,2010 through December 31,2012.
• A 62-beds medical & surgical intensive care unit
of 1800 beds tertiary hospital
17. Unplanned VS planned extubation Patients
• Data were retrospectively
collected from electronic
medical records.
• A total 230 episodes of
deliberate unplanned
extubation in 242 patients
from 41,207 mechanically
ventilated patients for 3
years(frequency 0.53%).
• 460 episodes in 460
patients with planned
extubation age, gender &
diagnosis-matched controls
were analyzed in this
case-control study.
18. Predictors related to unplanned extubation
in SNUH cases
Predictors associated with unplanned extubation
include
•Better motor response (OR 1.3),
•Admission route via ER(OR 1.8),
•Higher APACHE Ⅱscore(1.061),
•Mode of mechanical ventilation (CPAP, PSV: OR4.1,
SIMV:3.0),
•Peripheral O2 saturation(OR:0.9), heart rate(OR:
1.0), respiration rate(OR:1.0)
19. Predictors related to unplanned
extubation in SNUH cases
• Pain (OR:0.3),
• Agitation(OR:9.0),
• Delirium(OR:11.6),
• Night shift(OR:6.0)
&morning care
time(OR:0.5).
20. Predictors related to unplanned extubation
in SNUH cases
The patients’ & organizational outcomes of
unplanned extubation were
•Reintubation(OR;85.66)
•Poor discharge result(OR:0.2)
•Longer length of stay in the ICU (adj R-square:
7%)and a longer length of stay in the
hospital(adj R-square:4.3%).
21. High predictive factors of unplanned
extubation in SNUH cases
• Delirium, agitation, ventilation mode and night shift are
high predictive factors of unplanned extubation.
• The outcomes of unplanned extubation were
increasing reintubation, a poor patient outcome
at the time of discharge and poor
organizational outcome including longer length
of stay in the ICU and hospital.

TREAT
Treat pain with
analgesia therapy
Targeted sedation: RASS

Treat with sedatives for
light sedation
Treat patients with
nursing intervention:
•Reorient patients
•Use patient`s
eyeglasses, hearing aids
•Familiarize

mechanical ventilation
Assess: 2 fr ≥ duty, ASSESS
